Patented rMar. 1, 1932 UNITED STATES PATENT/OFFICE BRUNO nnrcnnrmor NUTLEY, NEW JERSEY TEltIPERATURE-CONTROLLED RELEASE roa rran-nxrmenrsnme ermmmns Application filed October 31, 1929 seria1no. 403,809.

acter wherein agrenade is employed to con tain suitable fire extinguishing substance, and which is releasably held in novel frame means through the instrumentality offusible con nections in the frame structure which are acted upon by the heat generated by a starting fire to release the grenade which thereupon falls and is shattered by contact with any hard object in its path to free the fire extinguishing substance contained therein. My present invention is a duplicate of my forfeited application Ser. #38874, filed June 12, 1925, allowed January 26, 1927, with Figure 3 cancelled.

I am aware that fuse devices have been employed in the art especially in connection with automatic sprinkler systems, but my present invention resides particularly in that combination which automatically releases a grenade from a symmetrical frame of pleasmg appearance and extremely simple design and constructlon, thereby ClISPQDSEHg with all valves, piping, pumps, and other intricate mechanism which is usually associated with systems of the aforementioned type. My I ,member of my frame and shows the fusible grenade furthermore, is so carried in the frame that it is protected from accidental jolts and jars, and since the frame is something more than a bracket retainer which must first be mounted on a base, it is not necessary to carefully instruct a. person in its use; it may simply be hung up on a ceiling or wall bracket or projection and when so disposed will act automatically in case of fire to release the grenade.

My frame is formed by novelly bending a single strand of wire to provide a retaining bail and a side protecting rib for a grenade as well as two loops or eyes for hanging the frame respectively either to a wall or ceiling or a room; third, the support for the grenade formed with more than one fusible connecfourth, my frame is especially designed to tionso that it is necessary for more than a spasmodicrise in temperature to obtain before my "grenade-Will be released, thereby avoiding accidental release of the same;

support an artistic screen, or fabric covering so that the artistic appearance of a room in a dwelling, theatre or the like will be preserved; fifth, my grenade support is formed with plural pivoted or hinged sections which are designed'to"fallaway upon fusing of the connections, thereby eliminating the disadvantages of so called spring releases.

The structural elements employed to accomplish the above and other results and objects will be hereinafter more fully described in detail and pointed out in the claims appended hereunto and forming a part of the specification, but the scope of my invention may only be determined by the limits defined in the clanns. I

In the accompanying drawings wherein is illustrated the preferred embodiment of my invention Figure 1 is a side View of my fire extinguishing device supported from a wall or other perpendicular surface;

Figure 2 is a side viewof'my fire extin guishing device supported from a ceiling or other horizontal surface; Figure 3is a perspective view of my grenade frame;

Figure 4 is a plan view of the supporting connections for its pivoted sections, and Figure 5 and Figure 6 show approved ways of suspendeding my grenades and shielding the sameto afford a pleasing and artistic appearance.

annular side protecting rib 6 around the grenade, a loop or eye 62 for hanging the frame on a wall or other perpendicular surface, and a bail 03 over the top of the grenade. Intermediate the endsof the baile3 is a second loop or eye 64 for suspending the 'loo grenade from a ceiling or other horizontal surface. The remaining portions of the wire strand form the hangers which extend down from the protecting rib e to a point adjacent the small end of the grenade a, and the respective terminals thereof are hooked as at 66 to retain there-between a support for the grenade. The support is formed of similarly and semi-circularly bent sections of wire 07 and 08, each of which is retained by the hooked end 66 of the hangers, and the two sections normally register with each other toform an annularband about the small end of the grenade with their respective free ends adjacent to the retained ends of the opposed section. Theseends are fixed by fusible solder connections 69 so that the sections will be released to swing down or .falleawayfto discharge the grenade when the temperature rises above the fusing point of the fusible solder connections 69 such as would be the case were a fire to start in the vicinity of the grenade and frame.

lVhen my grenades are disposed about a dwelling, church, theatre, or other building where artistic appearance is a consideration, they may be shielded by fabric shades 7,

similar to lamp shades, and in mounting my grenades on ceilings or the like decorative brackets orhooks g may beused. WVhen supported on a wall or the like hook supports-such as designated at it have been found'practical and desirable. V r

Vhile the operation of'my. fire extinguishing device is believed tobe apparent from the foregoing, emphasis is here made of the fact that it is entirely automatic in its operation, needsno instructions or skill in its disposition and use, is exceedingly simple in construction, and pleasing in appearance.

- WVhile in the foregoing, there has been illustrated and described such combination and arrangement of elements as constitute the preferred embodiment of my invention, it is nevertheless desired to emphasize the fact that interpretation of the invention should only be conclusive when made in the light of the subj oined claims;

7 Having described my invention and its objects with such attention to detail as will thoroughly, acquaint one skilled in the art with its construction and advantages, I claim I l 1. A frame for supporting a fire extinguishing grenade comprising a bent wire retaining body formed of asingle strand, said wire being bent to form a protecting rib, a top bail, and a plurality of eyes extending from the top 2. An article of manufacture for use in retaining fire extinguishing grenades comprising a frame formed of a single strand of wire, said frame having an annular rib, and depending hangers, the wire forming the same being bent about itself to form elements constituting each a half .of the annular rib, and the respective terminals constituting the hangers, the intermediate portion of one element being bent to form the bail, and plurally looped intermediate the extremities of the bail to form eyes for suspending the frame.

3. Means forreleasably supporting a fire extinguishing grenade comprising similarly formed wire members including a pivot end and a free end and adapted to be pivoted each to one end of a supporting frame and designed in assembly to support a grenade, said members being bent semi-circularly in opposite directions intermediate their extremities and registering thereat to form a circular seat for a grenade, the free terminals ofeach of the members being fusibly connected to the other adjacent the pivot end of the latter each said wire member being adapted to swing downwardly about its pivoted end upon breaking of the fusible connection to release the grenade.

In testimonywhereof, I aflix my signature hereunto.
